Global Optimization of Multi Radio Mesh Access Point Location in Underground Area

Abstract

This paper shows that with a proper placement of Mesh multi radio devices in a confined area, it is possible to reduce the congestion in the WMN (Wireless Mesh Network) by 50 to 60 percent according to the loaded traffic. The best portal deployment is obtained by minimizing the maximum traffic aggregation based on several constraints such as collision domain; routing and physical layer constraints. The different steps that must be fulfilled to reach this adequate deployment are clearly detailed. The effect of uneven resources utilization due to a non uniform spatial density of the workers in the confined area is also addressed. A well designed traffic distribution and a deployment algorithm for underground confined area are proposed and its effects on the WMN’s performance are evaluated by a Monte Carlo simulation.
